Tubaeform airscoop shroud, and drawing fan and scavenger fan are used cooperatively, that improves clearing machine goes out wind velocity, makes heavy construction
Air can fully convection current and purify in time in thing.
In order to achieve the above object, the solution of the utility model use is：A kind of fresh air purifier of high speed outlet air,
Including exhaust tube, filtration apparatus, drawing fan, scavenger fan and tubaeform airscoop shroud, the outlet side of the airscoop shroud and row
The inlet end connection of inflator, drawing fan are installed at the air inlet of airscoop shroud, and scavenger fan is installed in exhaust tube and is located at
The outlet side of exhaust tube, filtration apparatus are located in exhaust tube and are equipped with rectification in the inlet end of exhaust tube, the exhaust tube
Device, the fairing include the pointed cone portion of tubular straight sections and cone, air inlet of the pointed cone portion close to exhaust tube
End, the central axis of fairing is conllinear with the central axis of exhaust tube, and outlet duct is formed between fairing and exhaust tube.
Further, the air inlet open area of the airscoop shroud and the gas outlet area ratio of airscoop shroud are 5.6-2.8:1.
Further, the ratio between internal diameter of the end face diameter of the straight sections and exhaust tube is 1:1.4-1.7.
Further, the central axis in the pointed cone portion and busbar angle are 13-25 degree.
Further, the inlet end of the airscoop shroud is equipped with protection network.
The beneficial effects of the utility model are：
(1) airscoop shroud is tubaeform that the air inlet open area of airscoop shroud is more than outlet open area, and drawing fan is not only by outdoor
Air is discharged into airscoop shroud, and drawing fan can also carry out a degree of compression to air at the same time, makes the air pressure in airscoop shroud high
In atmospheric pressure, speed of the air by filtration apparatus is improved, and then the air output of clearing machine can be improved and go out wind velocity；
(2) outlet side of exhaust tube is equipped with scavenger fan, on the one hand can be to the air-flow in exhaust tube by scavenger fan
Secondary acceleration is carried out, further improves out wind velocity, building interior energy is formed enough cross-ventilations, on the other hand also
It can make the air pressure subatmospheric in exhaust tube, be used cooperatively with drawing fan so that filtration apparatus both ends form larger gas
Pressure difference, improves speed of the air-flow by filtration apparatus；
(3) since air-flow by being flowed to after filtration apparatus becomes very mixed and disorderly, so fairing is equipped with exhaust tube,
Outlet duct is formed between fairing and exhaust tube, disorderly air-flow is avoided by becoming stable during outlet duct again
Vortex is produced in exhaust tube reduces wind speed and air output；
(4) protection network is equipped with the inlet end of airscoop shroud, can so prevents that personnel touch flabellum by mistake in operational process, safety
Property it is strong, while be also avoided that major diameter impurity be inhaled into clearing machine damage equipment, it is highly reliable, it is sturdy and durable.

Embodiment
The utility model is further described below in conjunction with attached drawing：A kind of fresh air purifier of high speed outlet air, such as Fig. 1 and
Shown in Fig. 3, including tubaeform airscoop shroud 1, exhaust tube 2, filtration apparatus 3, drawing fan 4 and scavenger fan 5, the airscoop shroud
1 outlet side is connected with the inlet end of exhaust tube 2, and drawing fan 4 is installed at the air inlet of airscoop shroud 1, and scavenger fan 5 is installed
In exhaust tube 2 and positioned at the outlet side of exhaust tube 2, filtration apparatus 3 is located in exhaust tube 2 and is located at the inlet end of exhaust tube 2,
Fairing 6 is equipped with the exhaust tube 2, the fairing 6 includes the pointed cone of tubular straight sections 62 and cone
Portion 61, close to the inlet end of exhaust tube 2, the central axis of fairing 6 is conllinear with the central axis of exhaust tube 2 in pointed cone portion 61
(as shown in Figure 5), forms outlet duct 7 between fairing 6 and exhaust tube 2.
In the utility model, as shown in figure 4, the air inlet open area of airscoop shroud 1 is more than outlet open area, drawing fan 4
Not only outdoor air is discharged into airscoop shroud 1, drawing fan 4 can also carry out a degree of compression to air at the same time, make air inlet
Cover 4 in air pressure superatmospheric, improve speed of the air by filtration apparatus 3, and then can improve clearing machine air output and
Go out wind velocity.Experiment shows, when the air inlet open area of airscoop shroud 1 and the gas outlet area ratio of airscoop shroud 1 are 5.6-2.8:1
When, wind pressure in airscoop shroud 1 and reach optimum balance between the outlet open area of airscoop shroud 1, pass through filtering from airscoop shroud 1 at this time
The outlet air efficiency highest of device 3.5 one side of scavenger fan can carry out secondary acceleration to the air-flow in exhaust tube 2, further carry
Wind velocity is higher by, building interior energy is formed enough cross-ventilations, the air pressure in exhaust tube 2 on the other hand can also be made low
In atmospheric pressure, it is used cooperatively with drawing fan 4 so that 3 both ends of filtration apparatus form larger draught head, improve air-flow and pass through
Filter the speed of device 3.
Since air-flow by being flowed to after filtration apparatus 3 becomes very mixed and disorderly, so fairing 6 is equipped with exhaust tube 2,
Outlet duct 7 is formed between fairing 6 and exhaust tube 2, disorderly air-flow is kept away by becoming stable during outlet duct 7 again
Exempt to produce vortex reduction wind speed and air output in exhaust tube 2.Experiment shows, when central axis and the busbar angle in pointed cone portion 61
Rectification effect is best when being spent for 13-25, when the ratio between internal diameter of end face diameter and the exhaust tube 2 of straight sections 62 is 1:During 1.4-1.7,
Outlet duct 7 can carry out rectification to air-flow well and can pass through 2 row of exhaust tube in time by the gas of filtration apparatus 3
Go out, avoiding gas from being accumulated around pointed cone portion 61 increases air pressure.
As shown in Fig. 2, equipment is in actual use, airscoop shroud 1 is located at outdoor, and exhaust tube 2 passes through wall 9.Set in order to prevent
Personnel touch flabellum by mistake during received shipment row, while also avoid the impurity of major diameter from being inhaled into clearing machine damage device, lifting means
Safety and reliability, as a further improvement, the inlet end in airscoop shroud 1 is equipped with protection network 8.
Embodiment described above only expresses specific embodiment of the present utility model, its description is more specific and detailed,
But it should not be interpreted as limiting the scope of the present invention.It should be pointed out that for the common of this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.
